<p>A manufaturing process of a hydraulic accumulator, formed of two shells assembled to each other with interposition of a flexible membrane, wherein the mechanical element providing the connection of the two shells is subjected, before assembling said shells, to a prior prestress generating an effort bringing the two shells close to each other, this effort being superior to the maximum separation effort of the two shells to which is subjected the accumulator when subjected to the trial pressure.</p> |
